Hope it helps!! Mark this answer as brainliest if u found it useful and follow me for quick and accurate answers...

Step-by-step explanation:

Consider the given equations.

x+y=10 ………. (1)

x−y=2 ………. (2)

On adding equations (1) and (2), we get

2x=12

=> x = 6

On putting the value in equation (1), we get

6+y=10

y=10−6

=> y = 4

Answer 2

Answer:

a) x=6 , y=4

Step-by-step explanation:

x+y =10.. equation 1

x-y=2.. equation 2

adding both we get

2x=12

x=12/2

x=6

x-y=2

6-y=2

6-2=y

4=y
